The book of Job focuses mainly on the lessons Job learned as he went through the trials inflicted upon him as Satan tries to shake him loose from the faith and trust that he has in God. His friends tell him he is suffering because he has some secret hidden sin that he needs to confess, his wife tells him to just give up and curse God and die, but he refuses to let go of God. When we look at the beginning of the book we find the curtains drawn back so we can see what is happening behind the scenes (something that Job, his wife, and his friends did NOT have) observing interactions between God and Satan. In chapter 2 God is addressing Satan for the second time highlighting Job's faithfulness despite Satan "inciting [God] against him to ruin him without cause."
